Because of its scarcity, xenon is much more expensive than the lighter noble gases—approximate prices for the purchase of small quantities in Europe in 1999 were 10 €/L (=~€1.7/g) for xenon, 1 €/L (=~€0.27/g) for krypton, and 0.20 €/L (=~€0.22/g) for neon, [67] while the much more plentiful argon, which makes up over 1% by volume ...
Krypton is used in some photographic flashes for high speed photography. Krypton gas is also combined with mercury to make luminous signs that glow with a bright greenish-blue light. [39] Krypton is mixed with argon in energy efficient fluorescent lamps, reducing the power consumption, but also reducing the light output and raising the cost. [40]

The current national gas price average is $3.62 per gallon. The average cost of gas has decreased 15% in the last two years, from when it was $4.27 per gallon.
The kryptonium ion, KrH +, is an onium ion, consisting of protonated krypton. Kryptonium is known in dilute gas phase. [ 1 ] Although salts of the fluorokryptonium ion, KrF + , are known to exist, the existence of the kryptonium salts have not been proven.
